Determines when the DHCP service attempts to renew the lease on the IP address for this interface. If the attempt is not successful, DHCP tries again at the time specified by value of T2.
By default, this entry is equal to half of the lease term, as stored in the value of Lease. Also, by default, the value of T2 is equal to 7/8 (87.5%) of the value of Lease.
This entry is created and maintained by the DHCP client service when the service is enabled. Do not change this value. If you do, you might not be able to contact the DHCP server.
